That's not in the 360 demo. And for good reason. When reports of the graphical issues with the PS3 version of the game surfaced last month, Platinum Games made it clear that it developed the 360 version and handed off the data to Sega to port the game to the PS3.

Still, it's a bit surprising to see such a straight forward statement. This is also a bit surprising:

Looks like Platinum Games is trying hard to distance itself from the PS3 version!

Personally, I find that while the visual difference between the two demo versions is obvious, the PS3 version should still manage to sell any action fan on the final product. But these curious statements leave me concerned that the PS3 version will have some further ickiness that's not apparent in the demo.
